Deuce Bigalow (1999)

Continuity mistake: The first time Deuce goes to the pet store after being fired from the aquarium, he asks for sea snails from the bottom. She is wearing a white T-shirt with black jeans, clearly seen before, and during the act of sea snailing. The third time, at the end, she is clearly wearing a polka-dotted skirt. Fair enough, yet when they show her dipping in the aquarium again, you see that it is the same shot as before - she has her black pants on again.

Deuce Bigalow: Look, I think there's been a mistake.
Fluisa: Did you say steak?
Deuce Bigalow: No mistake.
Fluisa: Oh see now you got me all excited.
